We measure the quality of reconstructed frames using both PSNR and MS-SSIM [1]}. The bits per pixel (bpp) is used to measure the number of coding bits. Following the common evaluation setting in [2]}, the GoP sizes for the UVG dataset and HEVC standard Common Test Sequences are set to 12 and 10, respectively. In most previous methods for learned video compression, the H.264/H.265 is evaluated by using FFmpeg implementation, which performance is much lower than official implementation. In this paper, we evaluate H.265 and H.266 by using the implementation of the standard reference software HM 16.21 [3]} and VTM 8.0 [4]}, respectively. We would like to highlight that H.266 [VTM-8.0] is the latest mainstream video coding standard.
